Problems solved by technology

[0004] In view of the above-mentioned related technologies, the inventor believes that the interface properties between the ion storage layer and the electrochromic layer are quite different, so it is difficult for the ions in the ion storage layer to move quickly into the electrochromic layer when power is applied, resulting in electrochromic The color change response time of the chromogenic layer is longer, which affects the color change efficiency of the electronically controlled dimming glass

preparation example 1

[0044] The raw materials used in this preparation example can all be obtained from the market, wherein the lithium-based bentonite is selected from the lithium-based bentonite produced by Xinyang Wancheng New Material Co., Ltd.; the lithium hydroxide is selected from the lithium hydroxide produced by Jining Sanshi Biotechnology Co., Ltd.; modified Lithium-based bentonite was prepared according to the following steps:

[0045] (1) 40kg of lithium-based bentonite and 15kg of lithium hydroxide are uniformly mixed, and preheated at 180°C to obtain prefabricated lithium-based bentonite;

[0046] (2) Calcining the prefabricated lithium-based bentonite at 700° C. for 3 h, cooling the calcined product and pulverizing it to an average particle size of 15 μm to obtain a modified lithium-based bentonite.

preparation example 2-4

[0048] As shown in Table 1, the difference between Preparation Examples 2-4 and Preparation Example 1 lies in the amount of lithium hydroxide added.

Abstract

The invention relates to the technical field of glass products, and particularly discloses an intelligent dynamic dimming film and a preparation method and application thereof. The intelligent dynamic dimming film is prepared from the following raw materials in parts by weight: 50-70 parts of carrier resin, 20-30 parts of electrochromic filler, 20-30 parts of modified lithium-based bentonite, 12-20 parts of carbon nanotubes and 8-16 parts of a coupling agent. The color changing response time of the intelligent dynamic light adjusting film is shortened, and the color changing efficiency of the intelligent dynamic light adjusting film is improved.

Description

technical field [0001] The present application relates to the technical field of glass products, more specifically, it relates to an intelligent dynamic dimming film and its preparation method and application. Background technique [0002] Electrochromic glass is a new type of functional material. Transition metal oxides are usually added to electrochromic glass as electrochromic materials. Electrochromic materials can change color under the action of an applied voltage, thereby adjusting the light transmittance and light absorbance. Adjustment, which can not only play the role of anti-peeping, but also improve the lighting effect, has been widely used in many fields such as information, electronics, energy, construction and national defense. [0003] The Chinese patent with the notification number CN105759530B discloses an electronically controlled dimming glass, including a first transparent glass substrate layer, a first transparent conductive layer, an ion storage layer,...
